I've worked only on Qlik Sense so I'm not sure how much of my knowledge may be applicable in your setting. We usually cannot see other published apps scripts so there is no way to know where the data is coming from, what their original field name was vs. what was alias, etc. In order to see all this, we set up a security rule in the QMC so that anyone that is a content admin will be able to check out the script. If you set up some sort of rule like mine, you'll be able to have access to your users script, therefor showing you the data, sources, field names, any transformation on the script, etc. Hope this answers your question.
